Editing Guthan the Infested's equipment (section)

== Set effect ==
'''Infestation:''' Successful attacks have a 25% chance of healing the wielder an amount of Hitpoints equal to the damage dealt. For example, a hit for 20 damage will heal up to 20 Hitpoints if the effect occurs. It is also possible for the set effect to activate on an attack dealing 0 damage, although no health will be restored.

Players wearing Guthan's set with the amulet of the damned will be able to heal 10 above their base Hitpoints level.

Since the set effect triggers randomly, there is still a chance you need to eat food or teleport away to avoid dying. However, it is generally more consistent compared to the Saradomin godsword, especially in scenarios where you need to use another weapon's special attack.
